Description
The HEDS-9710/HEDS-9711 series
is a high performance, low cost,
optical incremental encoder mod-
ule. When operated in conjunction
with either a codewheel or
codestrip, this module detects ro-
tary or linear position. The encoder
module consists of a lensed LED
source and a detector IC enclosed
in a small C-shaped plastic package.
Due to a highly collimated light
source and a unique photodetector
array, the module is extremely tol-
erant to mounting misalignment.
The two-channel analog outputs and
5 V supply input are accessed
through four solder-plated leads
located on 2.54 mm (0.1 inch)
centers.
The standard HEDS-9710/HEDS-
9711 is designed for use with an
appropriate optical radius
codewheel, or linear codestrip.
Please contact the factory for
more information.
Applications
The HEDS-9710/HEDS-9711
provides sophisticated motion
detection at a low cost, making
closed-loop control very cost-
effective. Typical applications
include printers, plotters, copiers,
and office automation equipment.
Note:
Agilent Technologies
encoders are not recommended
for use in safety critical
applications, eg., ABS braking
systems, power steering, life
support systems, and critical care
medical equipment. Please contact
sales representative if more
clarification is needed.
Theory of Operation
The HEDS-9710/HEDS-9711 is a
C-shaped emitter/detector mod-
ule. Coupled with a codewheel, it
translates rotary motion into a
two-channel analog output.
Coupled with a codestrip, it trans-
lates linear motion into analog
outputs.
• Two-channel analog output
• Single 5 V supply
• Wave solderable
ESD WARNING:
NORMAL PRECAUTIONS SHOULD BE TAKEN TO AVOID STATIC DISCHARGE.
